Diese Uhr zeigt euch die Umgerechnete Zeit auf einem NEOpixel Ring an. Diese Seite dient nur als Ergänzung zu diesem Video https://youtu.be/mh1WkDiZuNk und stellt den Code zum kopieren und einfügen bereit.
Code im Globalen Bereich:
#include <ThreeWire.h>
#include <RtcDS1302.h>
ThreeWire myWire(6,5,4); // DAT (I/O), CLK (SCLK), RST (CE)
RtcDS1302<ThreeWire> rtc(myWire);
Code im Set up:
Serial.begin(9600); Serial.print("compiled: "); Serial.print(__DATE__); Serial.print(" "); Serial.println(__TIME__); rtc.Begin(); RtcDateTime compiled = RtcDateTime(__DATE__, __TIME__); printDateTime(compiled); Serial.println(); if (!rtc.IsDateTimeValid()) { Serial.println("RTC lost confidence in the DateTime!"); rtc.SetDateTime(compiled); } if (rtc.GetIsWriteProtected()){ Serial.println("RTC was write protected, enabling writing now"); rtc.SetIsWriteProtected(false); } if (!rtc.GetIsRunning()){ Serial.println("RTC was not actively running, starting now"); rtc.SetIsRunning(true); } RtcDateTime now = rtc.GetDateTime(); if (now < compiled) { Serial.println("RTC is older than compile time! (Updating DateTime)"); rtc.SetDateTime(compiled); } else if (now > compiled) { Serial.println("RTC is newer than compile time. (this is expected)"); } else if (now == compiled) { Serial.println("RTC is the same as compile time! (not expected but all is fine)");}
Code im Loop:
RtcDateTime now = rtc.GetDateTime(); printDateTime(now); Serial.println(); if (!now.IsValid()) { Serial.println("RTC lost confidence in the DateTime!"); } delay(100); } #define countof(a) (sizeof(a) / sizeof(a[0]))
